Lightroom Search & replace, Where is it?

Can we please have meta data search & replace/spell check in Lightroom for editing captions and descriptions etc. There are plug ins that will do this, but I think it is time this was a native feature of Lightroom. Iview media pro had this capability years ago, Lightroom developers should follow the lead that product gave. It was very flexible. As far as I can tell, this feature has been asked for since Release 2 of Lightroom. Well overdue.
